Question about Medela Cooler bag with 4 milk bottles and 1 cooling element

The Medela cooler bag with 4 milk bottles and 1 cooling element is specially designed for Medela milk bottles with a volume of 150 ml or 180 ml. However, it is possible to transport bottles with a similar diameter and a height of about 10 cm, which could also include bottles with a volume of 250 ml if they have these dimensions. However, you should make sure that the bottles fit well in the bag and are not too tight or too loose to ensure safe and efficient cooling.
